MACHINE FOR WASHING msrrns.

Application filed February 26, 1923. Serial No. 621,312.

This invention relates to dish washing machines, the primary object ofthe invention being to providenovel means for creating a swirling actionof the washing fluid in the tank of the machine, to cause foreign matterto be dislodged from the dishes scribed and claimed, it being understoodthat changes in the precise embodiment .of

the invention herein disclosed, may be made with an opening toaccommodate the tubuwithin the scope of what is claimed, withoutdeparting from the spirit of the inventron.

Referring to the drawings:

Figure 1 is a vertical sectional view through the machine.

. Figure 2 is a side elevational view of the water throwing head.

Figure 3 is a sectional view therethrough.

Figure 4 is a transverse sectional view through the water throwing head.

Referrin to the drawings in detail, the reference 0 aracter 5 designatesthe body portion of the washing machine, which is in the form of a tankprovided with a funnel-shaped bottom 6 that is formed with an opening topermit the shaft 7 to extend thereinto.

The body portion thereof is mounted on the support indicated generallyby the reference character 8 and embodies a plurality of vertical bars 9that have their upper ends disposed at angles as at 10 where they aresecured to the funnel-shaped bottom 6 in any .well knownmanner.

A flange 11 is formed on the outer surface of the funnel-shaped bottom 6and provides .anabutment for the leg members 9,

the lower ends of the leg members being shown as extending at rightangles as at 12 to provide feet. Mounted between the bars 9 is aplatform 13 that provides a support for the bearing 14 in which one endof the shaft 7 operates, the shaft '7, being provided with a beveledpinion 15 that meshes with the pinion 16 carried at-one end of the powershaft 17.

This power shaft 17 forms the movable element of the motor 18 which maybe supplied with electric energy from any suitable source of electricsupply, so that upon operation of the motor, the shaft 17 will heoperated to transmit rotary motion to the pinion 15, which in turnrotates the shaft 7.

Keyed or otherwise secured to the upper extremity of the shaft 7 are thepaddles 19 which may be adjusted longitudinally of the shaft to bringthe paddles to various positions with respectto the dishes supported in.the dish racks to be hereinafter more fully described.

Adjustably supported on the shaft 7 and disposed directly under thepaddles 19 is a water throwing head 20 which is in the form of areceptacle provided with a funnel-' shaped bottom 21 which is alsoprovided lar member 22, in which the shaft 7 is positioned, a set screw23 being provided for holding the head in various positions ofadustment.

As clearly shown by Figure 6 of the drawings, the head 20 'is providedwith a transversely extending partition 24 dividing thehead into lateralcompartments, there being provided an outlet opening 25 at one end ofeach compartment, and an inlet opening 26 in the funnel-shaped bottom 21of the head, the inlet openings being arranged in the bottom' wall ofthe respective compartments. In order that fluid may be forced into thehead 20, plates 27 are provided, which extend downwardly and aredesigned to scoop up the fluid during the rotation of the head 20 wherethe centrifugal force of the head throws the fluid from the outletopenings 25, forcing the fluid laterally and spraying the dishescontained in the dish racks.

Supported within thebody 5, is a wire frame indicated at 28, which frameis divided into compartments by means of the wire sections 29, thecompartments being of lengths to' accommodate the dishes to be washed sothat the dishes may be placed edge-wise within the racks, whereby theside faces of the dishes will be held in the path of travel of the fluidbeing thrown from the head 20, to the end that the foreign matteradhering thereto will be readily washed from the surfaces.

In order that the cleansing fluid may be placed in the body 5, hingedcovers 32 are provided, which permit of access to the interior of thetank and at the same time guard against fluid being thrown from the tankwhen the device is placed in operation.

To further insure the agitation of the cleansing fluid, a plurality ofupwardly extended flanges 33 are provided at the base of thefunnel-shaped bottom 6 of the body 5, which obstruct the passage of thefluid in a circular path to force the same upwardly.

A drain pipe 34 is in communication with the interior of theta-nk, andis provided with a valve member 35 to control. the passage of fluid fromthe tank when it is desired to draw the Water therefrom and replenishthe supply of water.

From the foregoing it will be seen that dishes may be placed in the dishracks, and

with the dishes in this position, it is obvious that when the motor isset into motion and the paddles 19 and head 20 rotates within the body5, a swirling motion of the cleaning fluid is set up which causes thefluid to be thrown against the surfaces of the plates with great forcedislodging foreign matter therefrom.

\Vhat is claimed as new is In a washing machine, a body portion, a shaftextending into the body portion, a hollow head mounted on'the shaft,said head having an inclined bottom, saidbottom having cut out portions,plates arranged adjacent to the cut out portions, said plates beingdisposed at oblique angles with respect to the upper edge of the hollowhead, said head having outlet openings, and a partition in the hollowhead dividing the hollow head into lateral passageways, leading to therespective openings.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature.
